To all whom t may concern.'

Be it known that we, JOSEPH Louis ADHE- MAR BoREL and EMILIE GRANGE, ne BOREL, citizens of the Republic of France, residing at 2 Rue Notre Dame, Annecy, Haute Savoie, in the RepublicA of France, have invented Y certain new and useful Improvements in Machines for Manufacturing Press-Buttons or the like, of which the following is a speci-4 cation.

The present invention relates to devices for manufacturi cr press buttons of the kind comprising a capike member containing a retaining spring, wherein the wire for the spring is first shaped in a device comprising a rod the end of which holds the shaped spring in a plane passing through the axis of the rod, whereupon a second rod is brought into proximity with the rst rod and the spring is transferred from the first to the second rod, whereupon the latter is withdrawn and serves to guide the spring to the cap likemember when the spring is forced into the latter.

One of the greatest difficulties encountered in the manufacture of press buttons comprising a cap like member and a spring, consists in the insertion of the latter two branches of which have to be inserted in two openings made laterally in the said cap like member,the 'said spring being manufactured on the same machine.`

According to the present invention use is made of the property possessed by lightly stamped metal springs of remaining on the end of the pressure member that has formed them, and in such a manner that the said springs may be transferred from the said pressure member when convenient.

VBy way of example the invention will now be described with reference to the accompanying drawing in which Figure 1 is a plan of the machine as a whole not in operation.

Fig. 2 is a plan of themachine as a whole in operation at the moment when the spring is descending under the action of the movable fork.

Fig. 3 shows in plan a view of the device not in operation that serves for the shaping of the spring.

Fig. f4 shows in plan a view of the device in operation that serves for the shaping of the spring.

Fig. 5 shows, in elevation not in operation,

the device that serves to put the spring in lts place and turn the edge of the cap like member over the spring. v

Fig. 6 shows, in elevation, in operation, the device illustrated in Fig. 5.

Fig. V7 shows inelevation a general view of the parts that serve to displace the spring for the purpose of making it pass from the parts that construct it to the parts that put it in its lace.

Fig. 8 1s a cross section along the line A A of Fig. 7.

Fig. 9 shows a front view and a section of a spring arranged in the cap like member of a press button before turning the edge of the cap like member over the spring.

Fig. 10 shows a front view and a section of a spring fitted into the cap like member of a press button.

It will be seen from the drawing, the machine forming as a whole the subJect matter of the resent invention is provided with a wire fee ing device a, with a counter shear b, and a shear c, and a matrix d arranged in a carriage e. The matrix d is actuated by a cam f, keyed on to the driving shaft g.

The matrix cl engages the cut piece of wire and is carried with it against the shaping device, the spring z' is shaped by the rod L and the sleeve j, tzlien the spring remains engaged horizontally astride of the nose of the rod h, as shown in dotted lines in Fig. 1, when the matrix d is withdrawn.

The device 7c as a whole serves for the placing of the spring z' in the cup like member and for turning the edge of the cap like member over the said spring, by means of a horizontal movement, directly under the shaping device. This movement of the device 7c, takes place integrally with the carriage m, by means of a cam n keyed on to a shaft o that receives its motion from the main shaft g by means of bevel wheels p.

The said tool c being directly under the shaping device, a fork g, pivoted at a", Fig. 7 operated by an eccentric s and a system of levers t, pushes the spring z', which descends from the nose of the rod 7L, by describing a circular arc of 90 from right to left and takes up a position vertically astride of the rod u.

At this moment the fork g ascends, and the carriage m withdraws the device c to the position shown in Fig. 1, while a counter punch o actuated by a cam carries a rod vthis Way held in itsfplace. Figs. V and 6 the rod u is provided at itsV outer end With a cavity capable of accommodating the stud arranged centrally of the cap like member.

VSprings .W, W Withdraw the rod u and the punch .e Vrespectively While the device la as a Whole is Withdrawn and the operation is Y completed. Y

Y It Willbe understood that various changes may be made in the machine .illustrated in the drawings Without departing from the scope of the invention dened in the appended claims. Y

What We claim and desire to secure by Letters Patent of the United States is l. A device for mounting the retaining spring inthe cap like member of press buttons, comprising, in combinationz-means for shaping the Wire of which the spring is to be formed, under such conditions that/ghe spring, after being shaped, remains engaged on the extremity of a rod in a plane passing through the axis of the latter, a spring carrying `rod capable of being brought underneath the said rod, a movable fork for the Vpurpose of disengaging the spring from the said rod and of engaging it on the spring carrying rod in such a Way as to place it astride ,of the latter, and means for pushing away the spring when it Vhas in this Way been placed on the rod, and of engaging it in the cap like member of thebutton and otturning the rim of the cap like member over the `spring engaged therein.

2. A device for mounting the retaining spring in the cap like member of press buttons, comprising in combination a shaping device and matrix arranged-in such a Way as to eect the formation of the Wire 'of which the spring is to beformed under such conditions that the spring, after being shaped, remains engagedV on .the extremity of the rod in ay plane passing through the axis of the'latter, a spring carrying rodeapable of being brought underneath thesaid rod, a movable fork for the purpose ofdisengaging the spring from its shaping rod and of engaging it on the spring carrying rod, in such a Way as to place it astride of the latter, asetting or flangingmatrix in which the cup-like member of the button is engaged and opposite to Which the rod car- Copies of this patent may be obtained for rying the shaped spring is brought, a set-V ting or ianging fpuneh in which the springcarrying rod is resiliently mounted, theV object of the rod being first to push the spring into the, cap-like member of the button, which is presented to it by the aforesaid matrix, and then to turn the rim of .thesaid cap like member over the springV engaged therein. g

`3. A device for mounting ythe retaining springin -th'e'cap like member of press buttons, comprising in combination :teed rollers for the Wire; means for cutting the Wire; a shaping matrix; and means for comL municating a reciprocating movement tothe said matrix; a shaping rod arrangedl opposite to the shaping matrix, alsleeve concentric With the saidirodjand cooperating With it Vand With the saidv matrix for the purpose of shaping `the Wire of which the spring is to be formed,"under such conditions that the spring,` after being-shaped, remains engaged onthe extremity of the shaping rod in a plane parallel tothe axis 'of the latter, a spring carrying rod arranged in such a Way as to admit of'being brought underneath the said shapingrod, a movable fork for the purpose of disengagingthe spring from its shaping `rodand of engaging it on the spring carrying rod, in such a Way as to place it astride of the latter: a setting or langing matrix in Which the caplike member of the button is engaged and opposite to -vvhich the rod carryingv the shaped spring is brought, a'setting or flanging device in which the said spring carry,- ing rod is resiliently mounted, the object of the rod being4 rst to push thespring into the cap like member of the button, which' is presented to it by the aforesaid matrix, and then to turnpthe rim of ,the said cap like member over the spring engaged therein, and means for communicating tothe setting or Hanging device and ito the spring carrying roda transverse movement of translation for the purpose of receiving the shaped spring and a longitudinal movement forfthe purpose of putting the springin position member.
